The CC2500 is a low-cost 2.4 GHz transceiver designed for very low-power wireless applications. The circuit is intended for the 2400- 2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band. The RF transceiver is integrated with a highly configurable base-band modem. The modem supports various modulation formats and has a configurable data rate up to 500 kBaud. CC2500 provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio.

It is an easily cascadable 8×8 monochromatic LED dot matrix display module with onboard MAXIM’s MAX7219 LED driver chip. The MAX7219 allows you to drive the LED matrix using only three I/O pins of Arduino or any other microcontroller. The LED matrix module used in Easy Matrix has a bigger dot size (5mm) and has the overall display dimensions of 60.2mm x 60.2mm (2.4″x2.4″). It is easily cascadable in series with the help of precisely aligned male and female header pairs located on the left and right sides of the display module. With lots of freely available Arduino libraries for MAX7219 chip, this module is easy to use in any Arduino project for displaying basic text and animation.

The Mega2560 Shield makes it easy for you to design custom circuits. You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard to quickly test circuit ideas without having to solder. It's got extra connections for all of the Arduino I/O pins, and it's got space to mount through-hole and surface mount integrated circuits. It's a convenient way to make your custom circuit and Arduino into a single module.
